CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit, under 35 U.S.C. § 119, of German patent application DE 10 2016 219 882.3, filed Oct. 12, 2016; the prior application is herewith incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION Field of the Invention

The invention relates to a domestic refrigeration appliance with a receptacle chamber for food, which is delimited by walls of an inner container. The refrigeration device has a pull-out device which is arranged on the inner container and is able to be pushed into and withdrawn from the receptacle chamber relative to the inner container. A container for receiving food is provided, the container being removably positionable on the pull-out device.

A configuration of this type is known, for example, from published, European patent application EP 2 564 729 A1. Therein, the pull-out device is formed only by opposing telescopic extenders arranged on vertical side walls of the inner container. A drawer placeable on these telescopic extenders engages with a rear tongue in the coupling element which has an indentation. In a front region of the drawer, a hole is formed on a web protruding laterally from a vertical side wall of the drawer, through which hole an engaging pin which is arranged on the running rail of the telescopic extender engages when the drawer is placed on the telescopic extenders. The engaging pin and the rear coupling element are both formed on the running rail of a telescopic extender and, in the installed state, the drawer is positionally fixed on the running rail and is therefore arranged thereon with an exact fit. In a design of this type, the removal of the drawer from the running rail is more difficult due to the exactly fitting mounting and is associated with a corresponding force application. The same applies for the placement of the drawer on the telescopic extenders. Apart from the placement and removal being made more difficult, damage to the coupling elements and increased wear can thereby also occur.

Containers are known in a great variety of versions. They can be simple drawers which are open and in which the same ambient humidity always prevails as in the remaining receptacle chamber. Furthermore, keep-fresh containers for food in domestic refrigeration appliances are known in which an ambient humidity different from that of the receptacle chamber or a different humidity level is settable and this can take place independently of the remainder of the receptacle chamber. For this purpose, the domestic refrigeration appliance typically contains a humidifying device with which a fluid mist can be generated that can be introduced directly into the storage region or the keep-fresh container. The humidifying device contains, as known, a tank with water from which the fluid mist is generated with an atomizer unit, for example a piezoelement, and is then conducted by a blower directly via a conduit connection and independently of the receptacle chamber into the keep-fresh container. The keep-fresh container is displaceably arranged in a housing of the domestic refrigeration appliance. Such embodiments are known from the prior art.

Furthermore, international patent disclosure WO 2011/026749 A2 discloses a corresponding refrigeration appliance with a vegetable compartment. A drawer for receiving the vegetables can be introduced into and removed from the interior. The drawer is coverable from above with a cover. In the closed state, the cover lies on angled upper edges of the drawer. A further panel is arranged above the cover on which a front strip is provided, on which an operating element is movably positioned. The operating element can be displaced parallel to the front strip and, for this purpose, is coupled to an inclined guide way in the form of a slit which is formed in the cover. Dependent upon this displacement of this pusher, a lifting of the cover takes place which is coupled by a corresponding mechanical coupling to the plate arranged thereabove.

Furthermore, from German patent DE 40 40 341 C2, a keep-fresh box with a closable cover is known. This box is also insert able into an interior of a domestic refrigeration appliance.

In both embodiments known from the prior art, it is intended to protect the refrigeration goods introduced thereinto, for example, in the form of vegetables, salad, meat, fruit and the like against undesirably rapid dehydration. The problems arising in this regard have previously been adequately described in DE 40 40 341 C2.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a domestic refrigeration appliance in which a pull-out device which is configured for the placement of a container, has a high degree of stability and is improved in its operability.

An inventive domestic refrigeration appliance contains a receptacle chamber for food which is delimited by walls of an inner container. The domestic refrigeration appliance further contains a pull-out device which is arranged on the inner container and is able to be pushed into and withdrawn from the receptacle chamber relative to the inner container. This occurs in the depth direction of the domestic refrigeration appliance. Furthermore, the domestic refrigeration appliance contains a container which is configured separately from the pull-out device and is configured for receiving food. The food-receiving container is removably position able on the pull-out device so that it is arranged there in a non-destructively releasable manner. Thus, the container can be reversibly removed from the pull-out device and replaced again.

It is an essential concept of the invention that the pull-out device contains a base panel for placement of the container which is configured multipart and contains a support panel and, arranged on opposite sides, as seen in the width direction of the domestic refrigeration appliance, support rails arranged thereon, wherein at least one support rail has at least one integrated coupling element for non-destructively releasable coupling of the base panel to at least one further component of the pull-out device. Thereby, the stability of the pull-out device is high, particularly in the region in which the container is placed. Furthermore, the modularity is great and the handling is simple for disassembly and reassembly. Thus, individual parts of the base panel and the pull-out device can be made simple and cleaned individually. Due to the smaller parts, these can also be placed in a dishwasher.

The base panel can be, in particular, a tray.

In particular, the pull-out device contains, as further components, holding elements which are configured as suspending elements for non-destructively releasable suspension of the base panel at separate pull-out rails of the pull-out device, and the base panel is connected to the holding elements by interlocking plug-in connections.

In particular, the pull-out device has a mounting cage for the container, containing a base panel and, seen in the width direction of the domestic refrigeration appliance, arranged thereon at opposite sides and separate from the base panel, holding elements as lateral cage walls, wherein the holding elements are configured as suspending elements for non-destructively releasable suspension of the mounting cage on pull-out rails of the pull-out device separate from the mounting cage. In this way, a stable accommodation of one or more containers is possible, so that a positionally secure arrangement of the container is enabled both in the unloaded and in the loaded state. In the unloaded state in which the container has a low weight, it is securely positioned even on sudden displacement of the pull-out device. In the loaded state, due to the mounting cage, a highly loadable construction is achieved which can also bear the weight while an easy-moving displacement of the pull-out device is achieved. Due to the individual design of the mounting cage, however, comprehensive accessibility of the container is always achieved, even in the pulled-out state, so that the handling of the container is simple and user-friendly.

The mounting cage can also be designated a mounting channel or a mounting seat.

Seen in the depth direction of the domestic refrigeration appliance, the mounting cage is preferably configured rearwardly open. Thereby, the access to the container is further improved and the weight of the mounting cage is reduced.

Preferably, the base panel is non-destructively releasably connected to the holding elements. Through this disassembly capability, the base panel can be easily cleaned in its individual parts.

Preferably, the base panel is connected to the holding elements by interlocking plug-in connections. These connections are mechanically stable and enable a particularly easy disassembly and reassembly.

In particular, the holding elements each have a support web on which the base panel is seated. Thereby, a mechanically stable positioning of the base panel is achieved but nevertheless the installation space is not undesirably restricted.

Preferably, at least one support web contains at least one receptacle into which a coupling element which is configured, in particular, on an underside of the base panel, is inserted for connecting to the holding element. Preferably, the receptacle is a through hole, having in particular a polygonal hole contour. Preferably, the coupling element is configured for insertion into the receptacle with an exact fit.

Preferably, the base panel is configured multipart and contains a support panel and support rails which are connected to the support panel, as seen in the width direction of the domestic refrigeration appliance, at opposite sides of the support panel. Thereby, the base panel can meet the different requirements at different sites and can thus, firstly, enable a stable connection to other components of the pull-out device and, secondly, enable a secure receiving of the container.

The container has at its rear region a coupling element which engages in a coupling pocket provided on the pull-out device, if the container is arranged on the pull-out device. By means of the coupling element and the coupling pocket, a tilt prevention device for the container is provided so that the container, in its mounted position placed on the pull-out device, cannot tilt about an axis oriented in the width direction of the domestic refrigeration appliance. Undesirable tilting of the container is thereby prevented.

It is provided, in particular, that a mounted position of the container in which the container is placed on the pull-out device is configured with a relative movement capability in relation to the pull-out device, having play defined as seen in the depth direction of the domestic refrigeration appliance. This means that, in this mounted position, which is also pre-determined, the container is not positionally fixed and thus also is not arranged on the pull-out device with an exact fit, but even in this mounted position, there exists a still possible relative movement between the drawer and the pull-out device. The tilt prevention device is configured such that over the entire range of this relative movement capability, the coupling element extends into the coupling pocket. This therefore also means that tilting of the container beyond this overall movement play in the mounted position is prevented. By means of such an embodiment, therefore, a simpler removal and replacement of the container from or into the pull-out device is achieved and nevertheless an undesirable tilting is prevented in all withdrawal positions of the pull-out device.

It is preferably provided that a pull-out stop element is provided on the pull-out device, by which the container is limited forwardly in its relative movement capability in relation to the pull-out device. By the pull-out stop element, the play in the depth direction is limited forwardly. Thereby, an undesirable further forward movement of the container relative to the pull-out device is prevented. An undesirable uncoupling of the tilt prevention device is thereby prevented.

Preferably, the play is less than 1.5 cm, in particular between 0.5 cm and 1.5 cm.

It is preferably provided that a stop is provided on the container, the stop being configured, on a movement of the container relative to the pull-out device, seen in the depth direction of the domestic refrigeration appliance, for contacting the pull-out stop element. A very simple embodiment for secure and robust prevention of a movement of the container undesirably far forward relative to the pull-out device is thereby achieved.

It is preferably provided that the stop is configured as a skid on an underside of the container. Thereby, an increased intrinsic mechanical stability of the stop is achieved and also a greater connecting area with the container or its underside. Thereby also, correspondingly greater forces which can occur with a corresponding impact can be absorbed. In particular, this skid extends in the depth direction of the domestic refrigeration appliance. It extends from the underside of the container downwardly, as seen in the height direction. It can be provided that this stop configured as a skid extends over at least half, preferably at least two thirds of the extent of the underside of the container, as seen in the depth direction. Preferably, this stop ends with its front end offset rearwardly, as seen in the depth direction, relative to a front end of the underside of the container or a floor of the container. Preferably, this front end of the stop is offset rearwardly by at least a fifth of the extent of the underside in the depth direction of the domestic refrigeration appliance relative to the front end of this underside.

In a further advantageous embodiment, it is provided that the coupling element is configured integrated into the stop and is therefore configured in one piece with the stop. Thereby, an intrinsically very stable component can be provided and it is also possible that the coupling element is formed from a very exposed site, specifically in particular, protruding rearwardly in the depth direction from a rear end of the stop, so that a particularly advantageous and secure coupling into the coupling pocket is enabled. Furthermore, with a configuration of this type, the coupling element can also be configured relatively small, for example, as coupling pin which can then also engage tongue-like into the coupling pocket. By this means, a structural space-minimizing solution is provided. Furthermore, with this embodiment of the integrated arrangement of the coupling element into the stop, an aligned positioning between the extent of the stop in the depth direction and the coupling element then extending further rearwardly in the depth direction is achieved.

It is preferably provided that, as seen in the height direction of the domestic refrigeration appliance, in the mounted position of the container on the pull-out device, the stop is arranged with a lower edge spaced from, and therefore arranged contactlessly relative to, this pull-out device. Thereby, a very low-friction embodiment is achieved since the stop slides along with its lower edge not on the pull-out device.

This is particularly advantageous if the container is placed at other sites on other components of the pull-out device and can correspondingly slide along there. For example, the container can then be placed slidingly directly on a support panel. In addition and instead thereof, it can also be provided that the container is contacted with guide elements at vertical side walls which it has and is seated thereon, wherein the guide elements can be, for example, components of holding brackets or holding elements which in turn, for example, are connected to a door of the pull-out device, in particular arranged on an inner side of said door of the pull-out device.

In an alternative embodiment, however, it can also be provided that the stop is seated contactingly with the lower edge on the pull-out device, which is possible precisely if no support panel is provided on which the container can be directly contactingly placed.

It is preferably provided that the pull-out device contains a slotted guide which is configured at least upwardly open wherein, in the mounted position of the container on the pull-out device, a stop provided on the container engages from above in the slotted guide and is guided. With this embodiment, a very simple and targeted placement and removal of the container onto or from the pull-out device is achieved and nevertheless a secure guidance is then also enabled in the mounted position by means of the play configured as defined in the depth direction. Furthermore, by means of the slotted guide, an undesirable displacement of the container relative to the pull-out device as seen in the width direction of the domestic refrigeration appliance is also prevented.

Preferably, the slotted guide is configured open not only upwardly, but also toward a vertical wall of the inner container. The above-mentioned advantages are thereby further improved.

In particular, the slotted guide contains a web or a slotted guide wall extending in the depth direction. The stop on the container is arranged, as seen in the width direction of the domestic refrigeration appliance, further outwardly and thus further toward the vertical side wall of the inner container than the slotted guide wall.

It is preferably provided that the coupling pocket is integrated into this slotted guide and, in particular, is configured as a rear end of the slotted guide and is integrated accordingly. Thereby, the coupling pocket fulfils the requirement of multifunctionality and components are therefore spared. The slotted guide wall opens, in particular, into the walls delimiting the coupling pocket.

In a further advantageous embodiment, it is provided that the pull-out stop element is integrated into the slotted guide, in particular, as a front end of the slotted guide. Thereby also, a component minimization is achieved and additionally the slotted guide is configured intrinsically more mechanically stable. The slotted guide wall opens, in particular, into the stop.

Through the positional arrangement of the coupling pocket and of the pull-out coupling element with regard to the integration into the slotted guide, the configuration of the play defined in the depth direction is also precisely pre-determined and simultaneously, the slotted guide is defined in its dimensions and its functionality.

It is preferably provided that the pull-out device contains at least one support rail on which the coupling pocket is provided. The support rail is, in particular, an elongate component, preferably made of plastics, which is configured in one piece. On the upper side of this rail, the coupling pocket is configured integrated protruding upwardly raised. Preferably, configured in this support rail is a slotted guide for guiding the container with the integrated coupling pocket. Hereby also, the component count can be reduced and the mounting effort and the mounting tolerances can be avoided and a simple and economical component can be produced, in particular as an injection molded component.

It is preferably provided that the pull-out device has two such separate support rails on each of which on opposite sides, corresponding coupling pockets are formed, in particular with corresponding slotted guides, so that coupling elements provided respectively on opposite sides of the container can engage in the coupling pockets.

In a particularly advantageous embodiment, it is provided that the pull-out device also has, in additional these support rails, a support panel which is arranged between the support rails and is connected to the rails. These support rails also form edge protection sleeves or impact protection elements for the support panel, which can also be made of glass. Thereby, a base element or base panel is provided, having a large area but also being thin in the height direction, on which the at least one container is securely place able. Precisely by means of this multipart base panel, the support panel can be made of a separate material, in particular glass and nevertheless the at least one coupling pocket, the at least one slotted guide and the at least one pull-out stop element can be integrated mechanically stably and simply into a component of the base panel separate therefrom, specifically a support rail.

In this regard, the pull-out device contains, in particular, a previously mentioned support panel on which the container is placed in its mounted position. In particular, in such an embodiment, the container has at least one positioning skid on its underside which, in the mounted position of the container, is seated directly on the pull-out device on an upper side of this support panel and makes contact with this upper side. The positioning skid is formed integrally on the underside and extends in the depth direction. Preferably, two such positioning skids are provided.

In an advantageous embodiment, it is provided that the container in its mounted position on the pull-out device, seen in the depth direction of the domestic refrigeration appliance, is arranged protruding forwardly in relation to the support rail and/or in relation to the support panel. This is a very advantageous embodiment, since a desired air circulation can thus take place in the receptacle chamber which then is not interrupted or hindered by the support rail and the support panel in this front region of the container. This air stream can thus also flow unhindered directly to this front region of the container and can there flow past so that a desired circulation of the air stream in the receptacle chamber is also achieved and it is not slowed or interrupted, precisely at this transition site between the support rail and/or the support panel, on one side, and the container, on the other. A particularly advantageous cooling in the receptacle chamber and thus also in the container is thereby achieved.

It is also particularly advantageous if in addition to the support panel and the support rails, the pull-out device contains separate holders and/or holding elements which are, in particular, panel-shaped angled components and extend rail-like in the depth direction of the pull-out device. In particular, these holding elements are each formed in one piece from metal. They are, in particular, suspension elements with which the support panel and the support rails are suspended on at least one pull-out rail of the pull-out device.

A pull-out rail is, in particular, a telescopic extender which contains a fixed rail and at least one movable running rail connected thereto and movable relative thereto. The fixed rail is fastened, in particular, on an inner side of a vertical side wall of the inner container. The pull-out rail is a component separate from the holding element.

By means of the support panel, the support rails and the holding elements which are connected to the base panel at opposite sides of the base panel in the width direction, in particular to the support rails, a mounting cage for at least one container is formed from these components. The mounting cage is laterally delimited by the holding elements which also form side walls of the mounting cage with their panel shape. In the depth direction rearwardly, the mounting cage is configured open. The mounting cage is hung or suspended with the holding elements on the aforementioned pull-out rails which are separate from the mounting cage.

In an advantageous embodiment, it is provided that the pull-out device is configured as a pull-out carriage which contains a door on which on an inner side of the door facing toward the receptacle chamber, rearwardly protruding rail-like angle brackets or holders are arranged which are, in particular, the aforementioned holding elements of the mounting cage. Mounted on these holders, in particular indirectly mounted, is the container. This means that in addition to the holders, further separate components are provided, in particular, the support rails and/or the support panel with which the container is then directly coupled and, via these support rails and/or the support panel, it is indirectly coupled to the holders. Preferably, therefore, the domestic refrigeration appliance also contains a tray or a type of compartment floor which contains the aforementioned support rails and the support panel. The door of the pull-out carriage is a front wall which, in the closed state of the pull-out carriage, represents a front outer part of the domestic refrigeration appliance.

In a further advantageous embodiment, it is provided that, between the inner side of the door and a front end of the support rails facing toward the inner side of the door and/or the support panel, a gap is formed. The aforementioned advantages with regard to the unhindered through flow of the air stream are thereby favored, including with this specific configuration with a pull-out carriage.

It is preferably provided that the container contains at least at one vertical side wall, a step so that an upper wall portion of the vertical side wall, as seen in the height direction of the domestic refrigeration appliance, is offset outwardly, as seen in the width direction of the domestic refrigeration appliance, relative to a lower wall portion of this vertical side wall. Thereby, a support plateau is created on the vertical side wall with which the container can be placed from above on a bearing part and/or a guide element. For example, this guide element can be the aforementioned rail-like holder and/or the holding element of the mounting cage.

The door in the embodiment of the pull-out device as a pull-out carriage is a front-side closing part which, in the closed state of the pull-out carriage, represents an outer part of the domestic refrigeration appliance. By means of the door, in the closed state of the pull-out carriage and therefore the completely pushed-in state of the pull-out carriage, the receptacle chamber is closed at the front side.

The container is preferably configured as a drawer so that it is a trough-like component and only accessible from above. It can also be configured as a keep-fresh container. For this purpose it has, in particular, a drawer and a cover with which the drawer is closable. The cover is lift able and lower able by an actuating mechanism, such that, dependent upon the position of the cover, moisture can escape from the keep-fresh container or is trapped therein. With the addition of fluid mist by an aforementioned humidifying device, a humidity level in the keep-fresh container can be set independently of the residual volume of the receptacle chamber.

The stipulations “above”, “below”, “in front”, “behind”, “horizontal”, “vertical”, “depth direction”, “width direction”, “height direction”, etc., indicate positions and orientations during proper use and arrangement of the appliance and with an observer positioned in front of, and looking in the direction of, the appliance.

Further features and embodiments of the invention are disclosed in the claims, the drawings and the description of the drawings. The features and combinations of features mentioned in the description above and the following features and combinations of features in the description of the drawings and/or shown in the drawings alone are usable not only in the respective combination given, but also in other combinations without departing from the scope of the invention. Embodiments of the invention which are not explicitly shown in the figures and described, but which arise and can be created through separate combinations of features from the embodiments described are therefore also to be considered as included and disclosed.

DETAILED DESCRIPTION OF THE INVENTION

In the drawings, the same or functionally identical elements are provided with the same reference characters.

Referring now to the figures of the drawings in detail and first, particularly to FIG. 1 thereof, there is shown a simplified representation of a domestic refrigeration appliance 1 which is configured for storing and conserving food. The domestic refrigeration appliance 1 in the exemplary embodiment is a refrigerator-freezer combination device but can also be a stand-alone refrigerator device or freezer device.

The domestic refrigeration appliance 1 comprises a housing 2 in which an inner container is provided which delimits with walls a first receptacle chamber for food, which is closable at a front side by at least one door, in the exemplary embodiment, two separate doors 3 and 4. The doors 3 and 4 are pivotably arranged on the housing 2 and can be pivoted outwardly independently of one another. The pivoting is herein enabled about a vertical axis and thus about an axis in the height direction (y-direction).

The receptacle chamber closable by the preferably two doors 3 and 4 is, in the exemplary embodiment, a refrigerator compartment.

Furthermore, the domestic refrigeration appliance 1 contains a further inner container 5 which, with its walls, delimits a further second receptacle chamber 6 which is separate from the first receptacle chamber and here is a freezing compartment. In the exemplary embodiment, it is provided that in the second receptacle chamber 6, a first pull-out carriage or drawer 7 can be pushed in and pulled out in the depth direction and thus in the z-direction of the domestic refrigeration appliance 1. It is preferably provided in the exemplary embodiment that the domestic refrigeration appliance 1 has a second pull-out carriage or drawer 8 which, in corresponding manner, can be pushed into the second receptacle chamber 6 and pulled out there from.

The following description will be made referring to the first pull-out carriage 7. The descriptions can advantageously also apply to the second pull-out carriage 8. The pull-out carriages 7 and 8 are pull-out devices of the domestic refrigeration appliance 1.

The first pull-out carriage 7 contains a door 9 which represents a front wall and also a front closing part and thus also an outer part of the domestic refrigeration appliance 1. The first pull-out carriage 8 further has a food-receiving container which herein is a drawer 10 which is thus configured as a trough-like container and is arranged for loading with food or for removal of food from above. The pull-out carriage 7 preferably further has, on opposite sides, pull-out rails 11 which are each arranged with a fixed rail on an inner side of vertical side walls of the inner container 5 and also each have at least one running rail. The pull-out rails 11 are therefore, in particular, telescopic extenders. The pull-out rails 11 are arranged on opposite sides of the drawer 10. It is preferably provided in the exemplary embodiment that the second pull-out carriage 7 has rail-like holders or holding elements 12 wherein in FIG. 1 only the rail-like holding element 12 at the right, on viewing from the front side, is visible, which is fastened to an inner side 13 of the door 9 facing toward the second receptacle chamber 6. These rail-like holding elements 12 are angle brackets that are preferably connected to the running rails. They are configured as plate-like and partially angled components made of metal. They are each hooked from above onto a running rail of a pull-out rail 11.

FIG. 2 shows a simplified sectional view of the region of the domestic refrigeration appliance 1 which represents the receptacle chamber 6 with the pull-out carriages 7 and 8. It is apparent that the door 9 and also the door of the second pull-out carriage 8 are not shown. A further container for food as a second drawer 14 which is associated with the second pull-out carriage 8 is also shown in FIG. 2. Both the pull-out carriages 7 and 8 are shown in the fully pushed-in state. The representation of FIG. 2 is a view in the negative x-direction and thus in the width direction of the domestic refrigeration appliance 1 so that in FIG. 2, the further rail-like holding element 15 positioned opposite the rail-like holding element 12 is visible.

It is further apparent that in the exemplary embodiment it is provided that in the freezing compartment or the second receptacle chamber 6, an introduction of cooling energy takes place by a module 16 which has, in particular, an evaporator 17 and a blower 18 and which is preferably arranged in its own housing 19. By means of this unit which represents a cooling device, by an evaporator 17, cooling energy is generated which is then circulated as an air stream 20 in the receptacle chamber 6 by the blower 18.

FIG. 3 shows a perspective view of the pull-out carriage 7 with the drawer 10 placed in the mounted position. On viewing from the front, the drawer 10 is completely covered by the door 9.

FIG. 4 shows subcomponents of the representation in FIG. 3 in an exploded view. The drawer 10 is configured as a single-piece plastics container on which, for example, a front strip 21 can be arranged.

As shown, herein the drawer 10 has two mutually opposed vertical side walls 22 and 23. The side wall 22 contains an upper wall portion 24 and, seen in the height direction, a lower wall portion 25. The two wall portions 24 and 25 are configured, seen in the width direction of the domestic refrigeration appliance 1, offset from one another, wherein for this a discrete step 26 is provided at approximately half the height of the side wall 22. The upper wall portion 24 is thus, seen in the width direction, offset further outwardly than the lower wall portion 25. The opposite side wall 23 is configured accordingly.

In the mounted state, the drawer 10 is seated, in an advantageous embodiment, on guide elements 27 and 28 of the holding elements 12, 15, wherein herein the placement of the drawer 10 on these guide elements 27 and 28 takes place precisely on these steps. The guide elements 27 and 28 are outwardly bent webs or wings. The guide elements 27 and 28 are oriented standing outwardly from upper edges 68 and 69 of respective panel-shaped basic parts 70 and 71 of the holding elements 12 and 15.

It is also recognizable that webs and/or positioning skids 30 and 31 are integrally formed onto a floor or an underside 29 of the drawer 10 and extend downwardly from this underside 29.

Furthermore, in FIG. 4, support rails 32 and 33 belonging to the pull-out device and thus to the pull-out carriage 7 are shown which are preferably one-piece plastics components. The support rails 32 and 33 are components separate from the holding elements 12 and 15. The holding elements 12 and 15 are preferably made of metal and are also, in particular, configured in one piece.

The support rails 32 and 33 are components of a support tray or tray 34, shown in a perspective view in FIG. 5, which is preferably present in the exemplary embodiment. The tray 34 contains, aside from the support rails 32 and 33, a support panel 35 which, in particular, is a glass panel, but can also be a plastics or metal panel. The support rails 32 and 33 extend in the depth direction over the whole extent of the support panel 35 and are thus preferably also edge-side borders of the support panel 35. By means of the support panel 35 and the support rails 32 and 33, a base panel 62, in particular of a mounting cage 61 (FIG. 6) is formed, on which the drawer 10 is place able. The support rails 32 and 33 grasp the support panel 35 on opposing edge sides so that they also represent a shock proofing. The support rails 32 and 33 also form the mechanical coupling elements to the holding elements 12 and 15.

By means of a base panel 62 which includes the support panel 35 and the support rails 32 and 33 and the holding elements 12 and 15, a receiving cage and/or the mounting cage 61 for the drawer 10 is formed. The mounting cage 61 is suspended on the pull-out rails 11 which are separate there from.

As can be seen from FIG. 5, provided on an upper side 36 of the support rail 32 facing toward the drawer 10, is a slotted guide 37 for guiding the drawer 10. The slotted guide 37 is configured open in the height direction and thus upwardly in the y-direction. It is also configured open in the width direction and thus in the x-direction toward the side and thus toward the adjacent vertical side wall of the inner container 5. The slotted guide 37 has a boundary wall and/or slotted guide wall 38 which projects upwardly from an upper side 36 and is configured extending straight in the depth direction. Formed at a rear end 39 in the depth direction is a coupling pocket 40 which is open forwardly but is closed upwardly in the height direction. The coupling pocket 40 is preferably integrated into the slotted guide 37 which means, in particular, that the walls delimiting the coupling pocket 40, specifically a rear wall 51 (FIG. 8) and a roof wall 48, open in one piece into the slotted guide wall 38. In the exemplary embodiment shown, the coupling pocket 40 then also represents the rear end 39 of the slotted guide 37.

Provided at a front end 41 of the slotted guide 37 is a pull-out stop element 42 which is, in particular, a stop web oriented in the width direction. In the exemplary embodiment, the pull-out stop element 42 delimits the slotted guide 37 forwardly and also opens integrally into the slotted guide wall 38.

Accordingly, at the further support rail 33 on an upper side 43 facing the drawer 10, a corresponding embodiment with a slotted guide and a corresponding coupling pocket and a corresponding pull-out stop element is realized, as formed at the support rail 32 and has been described in relation thereto.

It is thus preferably provided that the coupling pocket 40, the slotted guide 37 and the pull-out stop element 42 is provided, in particular integrated, in the support rail 32, 33.

In FIG. 6, the assembled state of the components according to FIGS. 4 and 5 is shown. It is herein apparent that the positioning skids 30 and 31 are seated directly on an upper side of the support panel 35.

FIG. 7 shows the representation of FIG. 6 in a vertical sectional representation in the x-y plane wherein in FIG. 7, only a partial portion of FIG. 6 is shown. As shown here, a lateral edge of the support panel 35 is grasped by the support rail 32 so that thereby a certain amount of edge protection is also formed.

It is evident that a stop 44 which extends downwardly at the underside 29 is formed integrally at the underside 29, in particular at a transition between the underside 29 and the side wall 22. The stop 44 is configured, in particular, as an elongate skid and preferably extends straight in the depth direction. It extends into the slotted guide 37 from above, as shown in FIG. 7. In the embodiment shown here, an essential point to be seen therein is that a lower edge 45 of the stop 44 is arranged, in the height direction and thus the y-direction, spaced from the pull-out device and/or the pull-out carriage 7 and, in particular, from the support rail 32, and in particular, from an upper side 46 of a floor delimiting the slotted guide 37. The contactless positioning enables a particularly freely moving coupling of a coupling element 50 (FIG. 8) formed integrally on the stop 45 with the coupling pocket 40. As also shown in FIG. 7, the stop 44 is arranged spaced, seen in the width direction, from the slotted guide wall 38 and is also spaced from the holding element 12.

Also shown in FIG. 7 is the roof wall 48 of the coupling pocket 40.

FIG. 8 shows a perspective view of the embodiments of FIGS. 6 and 7, but without the holding element 12, to allow a better view of the stop 44, the coupling pocket 40 and the pull-out stop element 42.

As shown by FIG. 8, the stop 44 extends as far as the rear end of the drawer 10. At a rear edge 49 of the stop 44, a coupling element 50 is formed on integrally, as mentioned above. The coupling element 50 is, in particular, a coupling pin arranged rearwardly in the depth direction which, in the mounted position shown in FIG. 8 of the drawer 10 on the pull-out device and thus on the support rails 32 and 33, is immersed in the coupling pocket 40 and extends thereinto so that, seen in the depth direction, the coupling element 50 overlaps with a roof wall 48. The coupling pocket 40 is delimited, as is more precisely visible in FIG. 8, by the rear wall 51 onto which the roof wall 48 leads.

It is further apparent that a front end 52 of the stop 44 is offset rearwardly in relation to a front end 53 of the drawer 10 and thus, in particular, also to the underside 29.

Furthermore, the stop 44 is configured, seen in the height direction; with a dimension such that an overlap with the height of the pull-out stop element 42 is achieved in the mounted position, in order in this regard also to achieve an effective pull-out stop.

FIG. 9 shows a side view of the representation in FIG. 8. It is apparent here that, in its mounted position, the drawer 10 is arranged, in the depth direction, on the support rails 32 and 33 with a play 54. The play 54 therefore enables a relative movement capability between the drawer 10 and the pull-out device; in particular, in the support rails 32 and 33 in this achieved mounted position of the drawer 10.

It is, in particular, very advantageous if the coupling element 50 and the coupling pocket 40 are configured such that an immersion of the coupling element 50 into the coupling pocket 40 is achieved over the entire movement path of the drawer 10 on the support rail 32 and the support rail 33. This means that over an entire play 54, the coupled state between the coupling element 50 and the coupling pocket 40 is maintained. This is particularly advantageous since thereby a simple removal of the drawer 10 from the support rails 32 and 33 as well as a simple mounting on the support rails 32 and 33 is enabled, although with this relative movement capability, an undesirable tilting of the drawer 10 about an axis oriented in the width direction is also prevented. It is then particularly advantageous if, as is made clear in FIGS. 9 and 10, the drawer 10 extends, as seen in the depth direction, beyond a front-side end 55 (FIG. 5) of the support rail 32 and a front-side end 56 (FIG. 5) of the support rail 33 and beyond a front-side edge 57 (FIG. 5) of the support panel 35, so that a spacing 47 in the depth direction results between a maximum front position of the drawer 10 and the edge 57. By this means, a gap 60 (FIG. 2) from the inner side 13 is formed and the unhindered flow of the air stream 20 is achieved.

FIG. 10 shows, for further elucidation, a position of the drawer 10 removed from the mounted position. By means of the play 54, it is more easily possible in this context to lift the drawer 10 with an upward pivot movement 58 (as indicated) from the support rails 32 and 33 and then to release the coupled state of the tilt prevention device 59 which is formed by the coupling element 50 and the coupling pocket 40 and to release the tilt protection state.

FIG. 11 shows a perspective view of the mounting cage 61 in an exemplary embodiment with subcomponents that are shown disassembled. The base panel 62 is herein separated from the holding element 15, wherein the connection between the base panel 62 and the holding element 15 is non-destructively releasable. The holding element 15 is shown with its panel-shaped basic part 70. On the lower edge situated opposing the upper edge 68, a horizontally inwardly positioned support web 64 is inwardly bent, on which in the assembled state, the support rail 33 is seated. As can be seen, in this support web 64 in the exemplary embodiment, not only one receptacle 65, but a plurality of such receptacles 65 is provided which here are configured as through holes, in particular, with a polygonal hole contour. In the assembled state, coupling elements 66 (FIG. 13), which are formed on an underside 67 of the support rail 33, in particular, integrally, engage in these receptacles 65. Configured between these coupling elements 66 and the receptacles 65 is a plug-in connection which is non-destructively releasable. In particular, the coupling elements 66 are adapted in their external geometry to the geometry of the receptacle 65, so that, in particular, an exactly fitting use and thus an exactly fitting insertion of the coupling elements 66 in the receptacles 65 is enabled. The holding element 12 and the support web 63 are configured accordingly.

As shown, according to the assembled representation of the mounting cage 61 in FIG. 12, the holding elements 12 and 15 are arranged on opposite sides of the base panel 62, as seen in the width direction and thus in the x-direction. Due to their panel-shaped configuration, in particular of the basic parts 70 and 71, the holding elements 12 and 15 are thus configured as lateral cage walls and thus as lateral borders of the mounting cage 61. The holding elements 12 and 15 are configured as suspension elements for non-destructively releasable suspension of the mounting cage 61 on pull-out rails 11 of the pull-out device that are separate from the mounting cage 61. For this, in particular, the suspension webs 72 and 73 are provided which in a vertical sectional representation and thus in an x-y plane, are configured channel-shaped and thus form a downwardly open channel. This can be configured, for example, as an inverted U-shape. In this context, the guide elements 27 and 28 are then specifically configured as these suspension webs 72 and 73 with their specific geometry.

As shown, in particular, in FIGS. 11 to 13, the mounting cage 61 is configured open, seen in the depth direction and thus rearwardly, which means that is has no rear wall. The mounting cage 61 is delimited at the front side by the door 9 which can thus also be considered the front wall of the pull-out carriage 7. In FIG. 12, the door 9 is not shown, although it is fastened, in particular screw-fastened, onto additional front flanges 74 and 75. These front flanges 74 and 75 can be separate parts, although they can also be integrated into the holding elements 12 and 15.

With regard to the suspension of the holding elements 12 and 15 on the pull-out rails 11, in particular on their running rails, it can also be provided that corresponding engagement elements couple with receptacles so that an interlocking or meshing takes place in the height direction between a holding element 12, 15 and a pull-out rail 11, so that the movement coupling between these components takes place on pushing back and forth in the depth direction.

In FIG. 14, a further exemplary embodiment is shown in a perspective view, in which two separate drawers 10 are arranged on the mounting cage 61. The containers herein also each have a cover 76 in addition to the drawers 10. The containers are herein keep-fresh containers in which by means of a humidifying device (not shown) of the domestic refrigeration appliance 1, an individual ambient humidity different from the remaining volume of the receptacle chamber 6 is settable. For this, the humidifying device contains, in particular, an atomizer unit, for example, a piezo-atomizer with which liquid, in particular water from a tank of the humidifying device is atomized and is then introduced by a blower as a fluid mist into the keep-fresh container. Each cover 76 is raisable and lowerable by means of an actuating mechanism. FIG. 15 shows the embodiment of FIG. 14 without the door 9.

In FIGS. 14 and 15, also shown purely by way of example in their positional arrangement and number, are three panel-shaped connecting flanges provided in the region of the pull-out rail 11, which are provided for fastening the pull-out rail 11 to a vertical side wall of the inner container.
